NGC 1407
NGC 1407 is an elliptical galaxy in Eridanus. It is at a distance of 76 million light years from Earth. It is the brightest galaxy in the NGC 1407 Group, part of the Eridanus Group, with NGC 1407 being its brightest member. NGC 1400, the second brightest of the group lies 11.8 arcmin away.
NGC 1407 is X-ray luminous, with high hot gas Fe abundance, and with evidence of recurrent radio outbursts. In the central area of the galaxy are present old stars, with mean age 12.0 ± 1.1 Gyrs, that are metal rich and with supersolar abundances of α-elements. Observations indicate that NGC 1407 hasn't recently undergone strong star formation activity. The galaxy hosts a supermassive black hole with a mass 1.12 ±0.42 billion solar masses, based on velocity dispersion.
The galaxy was discovered by 6 October 1785 by William Herschel.
